Abstract

In order to clarify fundamental mechanism of pulsed laser deposition (PLD) process, Mach-Zehnder interferometry and laser scattering spectroscopy were applied to YBa₂Cu₃O_7-x ablation plasma plume in atmospheric pressure. At the early stage ( < 10 μs), the KrF-laser ablation plume expands in agreement with the blast wave model, but later comes closer to the drag model. It is suggested that the yield of particulates in the ablation plume, which corresponds to the surface roughness of deposited film, increases with the laser energy density and the laser wavelength increase.
